"Stormtrooper X leads at least a dozen other outlaws, and all are considered very dangerous."

―A bounty posting on Stormtrooper X, located within the Imperial Enforcement DataCore[src]

Stormtrooper X and his pirate group were considered very dangerous by the denizens of the criminal underworld. He was a Human male, although his past remained a mystery to most. The Empire thought him important enough to issue a warrant for his arrest, though they offered no reward for his capture. His defining trait was a modified stormtrooper helmet that he wore with a large red "X" painted across the faceplate. The helmet contained a comlink with a broadband antenna that increased its range to 400 kilometers, as well as a signal interceptor that allowed Stormtrooper X to eavesdrop on encrypted communications. He could speak several different languages, including Basic, Dosh, Huttese, Rodese, and Sullustese.[1]

The cover of the 1997comic bookBoba Fett ½: Salvage, illustrated by Timothy Bradstreet, features an individual resembling Stormtrooper X in a law enforcement lineup. Like Stormtrooper X, this individual wore a stormtrooper helmet, albeit without a red "X" painted on it, and with normal clothing worn underneath. The back of the comic features a sketch of this cover and describes the individual as "some mysterious fellow with an appreciation for used stormtrooper armor."[2]
